GCC support for PowerPC VLE

[William Swashbuckler]

Hi,

I have recently read in several places that GCC now supports the
PowerPC VLE instruction set architecture as a target. However, I have
so far been unable to find any actual documentation on this? AFAICS
the online doc doesn't show any new target options, see e.g.

http://gcc.gnu.org/onlinedocs/gcc/RS_002f6000-and-PowerPC-Options.html

Can anyone point me in the right direction?

Thx

Thanks for the feedback. I based my "hope" on the below link:

It does look like patches for VLE has reached the GNU binutils -
probably what you are referring to. Please advise what good it is to
have VLE in the binutils, but not in GCC ? I thought one would imply
the other for it to make sense, but I may be wrong?

Also, it looks like somebody was looking at VLE and binutils almost
three years ago - but it seems to have taken a long time to mature.

I would really hope that someone would be adding VLE to GCC as it
would be very interesting to evaluate performance and code density
against e.g. ARM Thumb2 - VLE looks pretty powerful, and e.g. the
e200z0 core is a VLE-only core available as IP - besides being in
chips on the market today.
